So what is the difference between the "gmail" app that is on the Nexus and the "email" app that is on there as well? I'm not using the "email" app or have it setup and just the "gmail" for now. However I do not get any notifications in the top left when I receive an email nor does my LED light flash letting me know I have a new email. Is one better over the other? At one point last night both had been setup on the phone, but deleted my gmail account info from the email app and just now have the gmail app running. Do I need to use the email app instead to receive email alerts?
